Are there any plans to support symbolic coefficients for QubitOperator?

[andrewprojansky]

Hey all,

a bit curious as to if anyone has worked on adding support for symbolic coefficients for QubitOperator. I imagine a very simple use case would be in defining coefficient dependant Hamiltonians such as

from sympy import Symbol from openfermion.ops import QubitOperator x = Symbol('x') hamiltonian = x * QubitOperator('X0 X5') + 0.3 * QubitOperator('Z0')

Is there any planned support for this currently? If not, happy to try to work on it.

@andrewprojansky Thank you again for volunteering to take this on. Purely for planning & organization purposes, and without any expectations implied, could you let us know the state of things and whether we should keep you assigned to this issue?
